Same problem here as well, and indeed Nikita’s Google camera port fixes it with Google’s auto white balance set on in the settings.
@BertG do you really think we all should contact support? As I’ve found this workaround, I wouldn’t think it’s worth it (as well as with other issues which have a workaround like the muted microphone that can be reset with a reboot), especially knowing the support is overwhelmed since Android 10 Update and FP3+ release, and they’re working on software updates anyway…
